Katrin Hinrichs DVM, PhD

Katrin Hinrichs DVM, PhD

Professor and Patsy Link Chair in Mare Reproductive Studies

Dr. Katrin Hinrichs graduated from the University of California, Davis School of Veterinary Medicine in 1978. After private practice, she spent six years at the University of Pennsylvania’s New Bolton Center completing a residency and PhD. There, she began her research on hormonal requirements for pregnancy and embryo transfer in the mare. She spent the next 10 years at Tufts University School of Veterinary Medicine, teaching and conducting research on oocyte maturation and fertilization in the horse. Hinrichs joined the faculty at the Texas A&M College of Veterinary Medicine & Biomedical Sciences in 1998; she has a joint appointment in Veterinary Physiology and Pharmacology and Large Animal Clinical Sciences, and was named the Patsy Link Chair in Mare Reproductive Studies in 2005.

Dr. Hinrichs is best known to the horse-owning world for her unique contributions to equine cloning and in vitro fertilization (intracytoplasmic sperm injection, or ICSI). She and her group cloned the first horse in North America, and the third in the world. Their continued efforts have resulted in one of the highest reported success rates for production of live offspring following nuclear transfer in any species. Her laboratory has also pioneered many techniques to improve the success and clinical application of ICSI.  In addition, Dr. Hinrichs has contributed to the understanding of many other applicable procedures in equine assisted reproduction: helping to define requirements for equine embryo development; establishment of improved techniques to maintain viability of oocytes from injured or dying horses, so they may be transported to a specialty referral center for fertilization; improving understanding of the variables affecting oocyte maturation; development of a technique to biopsy horse embryos to determine the presence or absence of genetically-related diseases while maintaining the viability of the developing embryo; and establishment of techniques for improving success of embryo cryopreservation in horses. Her contributions have been widely employed by equine laboratories throughout the world.

Young Ho Choi DVM, PhD

Young Ho Choi DVM, PhD

Research Scientist

Dr. Young Ho Choi received his DVM from Seoul National University in South Korea in 1989 and he received his PhD from Gifu University in Japan in 1997. He completed his postdoctoral fellowship at the Obihiro University Agriculture and Veterinary Medicine in Japan and at Colorado State University in Colorado. Since 2000, he has been working at the Texas A&M College of Veterinary Medicine & Biomedical Sciences and he currently holds the title of research scientist.

Since 1990 Choi has had experience with in vitro fertilization in several species, such as: mice, pigs, cows and horses. His main research areas are assisted reproductive techniques, more specifically; intracytoplasmic sperm injection (ICSI) and cloning in the horse. He has published 32 papers with Hinrichs in the past decade, with the majority of them covering ICSI and cloning in the horse.


Dr. Sicilia Grady DVM, MS

Sicilia Grady DVM, MS

PhD Candidate

Dr. Sicilia Grady received her M.S. in equine reproduction at Texas A&M University in 2008, focusing on the effects of dietary supplementation of omega-3 fatty acids on semen characteristics in stallions. She received her D.V.M. from Colorado State University in 2012, and worked at the Oocyte Transfer Laboratory with Dr. Elaine Carnevale while attending veterinary school. Dr. Grady then completed a clinical internship at Durango Equine Veterinary Clinic in Arizona, working with board-certified Theriogenologist Dr. Lloyd Kloppe. Dr. Grady is currently a Ph.D. candidate in the Equine Embryo Laboratory at Texas A&M, performing research in conjunction with the Comparative Orthopedics and Regenerative Medicine Laboratory, on bone-marrow derived mesenchymal stem cells.

Dr. Paola Tinetti

Paola Tinetti, DVM, MS

Graduate Student

Paola Tinetti received her DVM from the University of El Salvador in 2007. After working at the El Salvador Zoo and with other organizations concerned with wild animals, she received a grant to study for her Master’s Degree at the Complutense University of Madrid, Madrid, Spain.  Dr. Tinetti is currently on a Fulbright scholarship in the Equine Embryo Laboratory, working toward her Ph.D. in Biomedical Science from Texas A&M University’s College of Veterinary Medicine & Biomedical Sciences.  Her interests include in vitro primordial follicle development in the horse as a model for endangered wild equine species.


Dr. Heloisa Canesin DeSiqueira

Heloisa Canesin, DVM, MS

Research Assistant

Dr. Heloisa Canesin received her DVM from Federal University of Lavras, Brazil, in 2011.  During her studies, she performed research in animal reproduction and worked in extension projects involving equine reproductive veterinary practice. In 2013, she received her MS in Animal Reproduction at Sao Paulo State University (UNESP Botucatu), Brazil, focusing on uterine hemodynamics in mares. Currently she is Research Assistant at the Equine Embryo Laboratory, conducting a project on equine oocyte vitrification. In addition, Dr. Canesin works in studies on assisted reproductive techniques performed at Laboratory, such as transvaginal follicle aspiration (TVA), oocyte maturation and manipulation, semen preparation, micromanipulation, staining and analysis.


Dr. Bart Leemans

Bart Leemans, DVM, MS, PhD

Research Scientist

Dr. Bart Leemans graduated in 2010 as a DVM at Ghent University, Belgium. After finishing his Master in Equine Veterinary Science, Ghent University, Belgium, he started a PhD program in equine reproduction at Ghent University, Belgium, in collaboration with Utrecht University, The Netherlands. His research was focused on the identification of physiological capacitation triggers of stallion spermatozoa in an equine oviduct explant model. After graduating his PhD in 2015, Dr. Bart Leemans joined the Equine Embryo Laboratory at Texas A&M University in January 2016 as a Post-doctoral Researcher working on stallion sperm capacitation and conventional equine in vitro fertilization as well as transvaginal follicle aspiration, oocyte manipulation and maturation and semen preparation.

Dr. Joao Luna

Joao Luna, DVM

Research Assistant

Dr. Joao Luna, graduated as a DVM at Universidade Estadual do Norte Fluminense – UENF, Rio de Janeiro, Brazil in 2013. While in school he participated on granted extension and research projects involving animal sanitation and disease control, large animal clinics, equine reproductive clinics and assisted reproduction techniques. He started at Texas A&M as a Research Scholar in February 2014 and since 2015 is a Research Assistant developing somatic cell sorting techniques from equine frozen semen as well as immunocytochemistry, transvaginal follicle aspiration and oocyte manipulation and maturation.


Kindra Rader

Kindra Rader

Program Coordinator

Ms. Kindra Rader is originally from Cheyenne, Wyoming.  She attended Laramie County Community College, where she competed on the horse show and horse judging teams while obtaining her Associates Degree in both Equine Science and Equine Training Management. In 2012, she obtained her Bachelors of Science degree in Animal Science at Oklahoma State University.  Ms. Rader breeds quality reining horse prospects and has worked in numerous positions within the equine industry, including yearling sales preparation for Vista Equine Colorado, Royal Vista Ranches, and Lazy E Ranch with attendance to select yearling sales across the country. She has also served as foaling attendant for Royal Vista Ranches LLC, and breeding farm manager for Fox Meadow Farm Reining Horses in Oklahoma. This has helped her build a network of friends and mentors that have fueled her passion for horses and expanded her knowledge of horsemanship, equine physiology and the horse industry. Ms. Rader began working as a Technician at the Equine Embryo Laboratory at Texas A&M University in 2013 and now serves as the Program Coordinator for the Laboratory. Ms. Rader oversees all aspects of the clinical ICSI program including but not limited to transvaginal follicle aspiration procedures, oocyte recovery from isolated ovaries post mortem, media preparation, oocyte maturation, and coordination of embryo transfer, vitrification, and genetic biopsy procedures.  Ms. Rader also serves as the laboratory liaison between the Equine Embryo Laboratory, the Large Animal Hospital, and the Section of Theriogenology. She plans to pursue a Master’s in Business Administration in 2016.
